Silene lemmonii is a perennial herb producing several stems and shoots from a woody, branching caudex. The decumbent or erect stems may be up to 45 centimeters long and are hairy, the hairs on the upper parts glandular. Most of the leaves are located low on the plant and are oval to lance-shaped, measuring a few centimeters in length; smaller leaves may occur on the upper stem. The inflorescence bears 1 to 7 nodding flowers on sticky glandular stalks.
|
|
The more numerous fertile flowers are cleistogamous (they are self-pollinating and never open), and are hidden beneath the leaves. The flower stalks (peduncles) of the cleistogamous flowers are short, 2-5 cm long, and curved downward. The calyx forms a shallow, hairy hypanthium, which is divided into 5-6 lobes of unequal size, the 3 larger lobes are toothed (serrate). The stem is decumbent/creeping, "several inches" in length, with a densely tufted terminal portion which bears both leaves and flowers.
|
|
Like all Downingia, the stem is decumbent to erect with leaves that are along the stem and often fall before the plant flowers. The flowers are not sessile and in a spike inflorescence with individual flowers having a corolla length of 10 to 12 mm. The corolla is glabrous and has 2 distinct lips, the upper with 2 lobes and lower with 3 lobes. The upper lobes are narrowly triangular or elliptic in shape while the lower lobes are obtuse and abruptly toothed.

This mat-forming species is one of the few species in the genus that do not have the typical leaf-tip diadems. It is also one of three species that have leaves entirely covered in dense hairs (together with T.fergusoniae and T.pygmaeum). Its growth form is erect to partially decumbent (but not mat-forming like T.pygmaeum). In its general growth-form, it is most similar to T.gracile, which differs in having leaves with bead-like epidermal cells and not hairy.

The main features used to distinguish Nylanderia queens from other Prenolepis genus-group genera come primarily from the mandibles and scapes. Like workers, Nylanderia queens have erect macrosetae on their scapes. However, the macrosetae are often not as distinct as in workers because the macrosetae are often shorter and usually surrounded by a thick layer of decumbent pubescence. When considering genera such as Euprenolepis and Pseudolasius in which queens also possess macrosetae on the scapes, differences in mandibular tooth count will distinguish Nylanderia queens.

The different species of this series show clear and distinct adaptations to their different natural habitats. The climbing aloe species that are indigenous to regions with tall, thicket vegetation are tall and erect - often with hooked, recurved leaves that allow the aloes to anchor their branches and climb up through trees and thickets. In contrast, the species from drier regions with low, sparse, fynbos vegetation tend to be more "decumbent", rambling along the ground - with no need for their leaves to be recurved.Reynolds, G: The Aloes of South Africa.

In Burgundy, the use of (highly productive) Pinot droit clones is reportedly still widespread in inferior, Village appellation, or even non-appellation, vineyards and Pinot droit is consequently regarded, arguably with very good reason, as a (genetic) sub-form significantly inferior to classical, decumbent, 'Pinot fine' or 'Pinot tordu', clonal lines of Pinot. Frühburgunder (Pinot Noir Précoce) is an early-ripening form of Pinot noir. Across the Pinot family, ripening in typical climates can be dispersed by as much as four, and even six, weeks between the very earliest (including Précoce) clones and the very latest ripening. Virus infection and excessive cropping significantly add to the delaying of Pinot noir ripening.

It is a cycad with an arborescent habit, with an erect or decumbent stem, up to 2.5 m tall and 35-40 cm in diameter, sometimes with secondary stems originating from basal suckers. The pinnate leaves, arranged in a crown at the apex of the stem, are 1–2 m long, supported by a stem about 23 cm long, which has a characteristic reddish ring at the base; they are composed of numerous pairs of lanceolate, leathery leaflets, up to 25 cm long, with a toothed margin and a pungent apex, arranged on the rachis at an angle of 70°. It is a dioecious species, with male specimens presenting from 1 to 5 sub-conical, pedunculated, 25–40 cm long and 5–9 cm broad cones, and female specimens with 1-3 ovoid cones, 35–40 cm long and 18– wide 20 cm, light green color. The seeds are roughly ovoid, 3.5-3.8 cm long, covered with an orange-red sarcotesta.

It is an arborescent plant, with erect or decumbent stem, without branches, up to 2.5–3 m tall and with a diameter of 35–45 cm, covered with tomentose cataphylls. The pinnate leaves, arranged in a crown at the apex of the stem, are 150–200 cm long, composed of about 50 pairs of lanceolate leaflets, with margins endowed with small spines and arranged on the rachis at an angle of 45-80 °. It is a dioecious species, endowed with 1-4 fusiform male cones, sessile, green in color, 30–50 cm long and with a diameter of 7–10 cm, with broad and rhombic- shaped microsporophylls, and 1-2 female cones, ovoid, always green, but 35–45 cm long and with a diameter of 15–20 cm, with macrosporophylls with a warty surface. The seeds have an oblong shape, are 30–35 mm long, have a width of 8–23 mm and are covered with a brown sarcotesta.

The worker caste of D. boltoni shares many important character states with that of its sister species D. armigerum, including the heart-shaped head, the large eyes located on a low cuticular prominence, the number of apical mandibular teeth, and general habitus. Daceton boltoni differs from D. armigerum by the absence of a specialized row of thick setae on the inner (masticatory) margin of the mandibles; by mandibles that are slightly shorter and more stout, which could indicate differences in prey preferences between the two species; by a broad gap, when seen in profile, between the bases of the fully closed mandibles and the margins of the head capsule; by shallow depressions adjacent to and ventral to the mandibular insertions; by long and simple lateral pronotal spines; by a weakly impressed metanotal groove; and by subdecumbent to decumbent hairs on the tergite of abdominal segment IV. Behaviorally, D. boltoni appears to be very similar to D. armigerum. However, drop tests conducted at the type locality indicate that D. boltoni individuals exhibit weak and inconsistent aerial gliding behavior relative to those of D. armigerum. Gynes and males are unknown.
